The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading an interface user to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on the device with the privileges of the user. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/ cisco-sa-20190417-wlc-csrf Affected Products o Vulnerable Products This vulnerability affects Cisco Wireless LAN Controllers that are running a vulnerable software release. For information about which Cisco WLC Software releases are vulnerable, see the Fixed Software section of this advisory. Determining the Cisco WLC Software Release To determine which Cisco WLC Software release is running on a device, administrators can use the controller web interface or the CLI. To use the web interface, do the following: 1. By using a browser, log in to the controller web interface. 2. Click the Monitor tab. 3. Click Summary in the left pane. 4. Under Controller Summary , the Software Version field shows the release number of the software that is currently running on the device. To use the CLI, log in to the controller by using Telnet, issue the show sysinfo command, and then refer to the value in the Product Version field of the command output. The following example shows the command output for a device that is running Cisco WLC Software Release 8.3.102.0: (wlc)> show sysinfo Manufacturer's Name.............................. Cisco Systems Inc. Product Name..................................... Cisco Controller Product Version.................................. 8.3.102.0 Bootloader Version............................... 1.0.1 Field Recovery Image Version..................... 6.0.182.0 Firmware Version................................. FPGA 1.3, Env 1.6, USB console 1.27 Build Type....................................... DATA + WPS . . . Products Confirmed Not Vulnerable Only products listed in the Vulnerable Products section of this advisory are known to be affected by this vulnerability. Details o More information is in Understanding Cross-Site Request Forgery Threat Vectors . Workarounds o There are no workarounds that address this vulnerability. Fixed Software o Cisco has released free software updates that address the vulnerability described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license: https://www.cisco.com/c/en/us/products/ end-user-license-agreement.html Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades. When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page , to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release.

The attacker would need to have valid administrator credentials on the device. These vulnerabilities are due to incomplete input validation for unexpected configuration options that the attacker could submit while accessing the GUI configuration menus. An attacker could exploit these vulnerabilities by authenticating to the device and submitting crafted user input when using the administrative GUI configuration feature. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. These vulnerabilities have a Security Impact Rating (SIR) of High because they could be exploited when the software fix for the Cisco Wireless LAN Controller Cross-Site Request Forgery Vulnerability is not in place. In that case, an unauthenticated attacker who first exploits the cross-site request forgery vulnerability could perform arbitrary commands with the privileges of the administrator user by exploiting the vulnerabilities described in this advisory. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

The vulnerability exists because the affected software does not properly clear previously assigned session identifiers for a user session when a user authenticates to the web-based interface. An attacker could exploit this vulnerability by using an existing session identifier to connect to the software through the web-based interface. Successful exploitation could allow the attacker to hijack an authenticated user's browser session on the system. There are no workarounds that address this vulnerability.
